The Control of Ball Mill Loading

The amount of balls in the ball mill refers to the number of steel balls in the cylinder when the ball mill is grinding. In order to ensure the grinding efficiency of the ball mill, the ball loading volume needs to be tested according to the actual situation of the concentrator, and the ball loading volume that meets the situation is calculated.

The ball mill steel ball is a consumable of the concentrator. Every time it is necessary to supplement or replace the steel ball to ensure the grinding quality and grinding rate of the ball mill. So how do you control the amount of balls loaded by the ball mill during one ball loading and subsequent replenishment or replacement of steel balls?

1. The important significance of ball milling. The ball mill is one of the necessary equipment for the beneficiation plant. The investment in the ball mill is quite large in the entire beneficiation plant. Therefore, its working efficiency can directly affect the entire production line. So what does the ball mill mainly rely on for ore grinding? It is the steel ball. The quality of the steel ball, the quantity of the ball and the size of the ball will affect the normal performance of the ball mill. In the actual production process, if the ball mill is loaded with too many balls, the steel balls are likely to overlap each other and lose the grinding effect, and some of the steel balls are thrown off without raising the height, which reduces the overall grinding capacity. It will increase the power consumption of the ball mill; if the ball mill is too small, there is not enough capacity to grind the material between the steel balls, which will extend the working time of the ball mill, which will not only consume a lot of energy, but also cause the problem of low grinding efficiency. The rationality of ball milling is very important.

2. What is a reasonable range of steel balls for the ball mill? Under normal circumstances, the volume of the ball mill steel ball is lower than the horizontal line in the cylinder. It is better to control the ball volume at about 40~50%. At this time, the ball volume productivity is higher, and the ball volume can be controlled for smaller ball mills at about 35%, this can effectively ensure that the steel balls in the ball mill can fall freely, so that the steel balls have a greater impact and complete the grinding of materials.

The control range of the ball mill loading amount mentioned above is only the standard given under normal circumstances. It needs to be determined according to the design situation during use, and a reasonable plan can be determined. The amount of balls in the ball mill refers to the number of steel balls in the cylinder when the ball mill is grinding. In order to ensure the grinding efficiency of the ball mill, the ball loading volume needs to be tested according to the actual situation of the concentrator, and the ball loading volume that meets the situation is calculated.
